[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] It should be understood that although the terms upper, middle, lower, top end, one end, etc. appear in the present text to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for the purpose of understanding, and are not used to define any direction or sequence limitation.

[0034] As Figures 1-11 shown, an automobile air conditioner electric air outlet mechanism includes a shell 5, a sponge 3 attached to the outside of the shell 5 to reduce vibration and noise, a main blade group 6 and a secondary blade group 9 rotatingly arranged inside the shell 5, and a drive module 1 driving the main blade group 6 and the secondary blade group 9 to swing, the drive module 1 being fixed on the shell 5 through a drive module support 2.

[0035] Further, the drive module 1 includes at least one transmission part 81, and the drive module 1 synchronously drives the main blade group 6 and the secondary blade group 9 to rotate through a transmission mechanism 4;

[0036] The transmission mechanism 4 comprises a main vane transmission part 10 and a secondary vane transmission part 8, the main vane transmission part 10 and the secondary vane transmission part 8 are in transmission connection with the transmission part 81 respectively, the main vane group 6 is connected with the main vane transmission part 10 and is constrained to swing left and right about the X axis, the secondary vane group 9 is connected with the secondary vane transmission part 8 and is constrained to swing up and down about the Y axis, and in one rotation cycle of the transmission part 81, the main vane group 6 performs a swing action between the limit positions through the main vane transmission part 10, and the secondary vane group 9 performs a swing action between the limit positions multiple times through the secondary vane transmission part 8, the left and right rotation of the main vane group 6 and the up and down rotation of the secondary vane group 9 are controlled simultaneously through one driving module 1, not only the number of the driving module 1 is reduced, the cost is saved, but also the structure is compact, the occupied space is small, and the air outlet only needs to drive the driving module 1 to rotate in one direction to realize the air sweeping mode, and the comfort of passengers is improved.

[0037] As shown in Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 Further explained about the transmission mechanism 4 and the main vane group 6 in the embodiment, the transmission mechanism 4 comprises the main vane transmission part 10 for driving the main vane group 6 to swing and the secondary vane transmission part 8 for driving the secondary vane group 9 to swing, the main vane transmission part 10 is in transmission connection with the output end of the driving module 1, and the transmission part 81 is arranged between the main vane transmission part 10 and the secondary vane transmission part 8, so that the main vane transmission part 10 and the secondary vane transmission part 8 rotate synchronously.

[0038] Specifically, since the output end of the driving module 1 is in transmission connection with the main vane transmission part 10, and the transmission part 81 is arranged between the main vane transmission part 10 and the secondary vane transmission part 8, the main vane transmission part 10 and the secondary vane transmission part 8 are engaged with the transmission part 81 respectively, so that one driving module 1 drives the main vane group 6 and the secondary vane group 9 to rotate simultaneously, compared with the transmission electric air outlet, the manufacturing cost is lower, and the volume of the whole air outlet is smaller, which is more convenient to install.

[0039] Further, the main blade driving part 10 comprises a first output gear 7 connected with the output end of the driving module 1, a rotating base 72 connected with the first output gear 7, a sliding base 74 connected with the main blade group 6, and a universal rod 73 connecting the rotating base 72 and the sliding base 74. The output end of the driving module 1 is connected with the connecting part 71 of the first output gear 7, so as to drive the first output gear 7 to rotate. The first output gear 7 is connected with the rotating base 72, and the universal rod 73 is connected with the rotating base 72. Since the rotating base 72 extends along the radial direction and has a rotating arm, the universal rod 73 is eccentrically connected with the rotating base 72, and the two ends of the universal rod 73 are eccentric to the rotating center of the first output gear 7. When the rotating base 72 rotates, one end of the universal rod 73 rotates along a circle, and the sliding base 74 slides back and forth, so as to drive the main blade group 6 to swing and realize left and right wind guiding.

[0040] The main blade group 6 comprises a main blade connecting rod 61 and a main wind guide 62 arranged on the main blade connecting rod 61. The sliding base 74 is formed with a sliding part 75 for sliding cooperation with the main blade connecting rod 61, and the sliding part 75 is formed with a sliding groove 751 for inserting the main wind guide 62, so that the sliding part 75 can slide up and down along the main blade connecting rod 61. The universal rod 73 rotates under the action of the rotating base 72, drives the sliding part 75 to move left and right horizontally, and drives the main blade connecting rod 61 to move horizontally. Since the main wind guide 62 is arranged on the shell 5 and is connected with the main blade connecting rod 61 through a rotating rod, the main wind guide 62 can swing along with the horizontal movement of the main blade connecting rod 61.

[0041] Preferably, the two ends of the universal rod 73 are formed with a first ball head 732 and a second ball head 731. The first ball head 732 is arranged in the rotating base 72, and the second ball head 731 is arranged in the sliding base 74. Since the two ends of the universal rod 73 are formed with the first ball head 732 and the second ball head 731, one end of the universal rod 73 can rotate along a circle with the rotating base 72, and the other end can rotate in the sliding base 74, so as to improve the smoothness of the swing of the main wind guide 62.

[0042] Further, the sliding base 74 and the rotating base 72 are connected with a fixing block 76 and are formed with a spherical rotating cavity. The universal rod 73 is fixed in the spherical rotating cavity, so that the universal rod 73 can rotate on the sliding base 74 and the rotating base 72 in a spherical surface.

[0043] As Figure 9 , Figure 10 , Figure 11As shown, specifically, when the air outlet is in its initial state, both the main blade group 6 and the secondary blade group 9 are in their extreme states. When the main blade group 6 is in its right extreme position, the universal joint 73 is parallel to the X-axis. When the drive module 1 starts operating, the first output gear 7 rotates, and the rotating seat 72 rotates synchronously with the first output gear 7. The rotating seat 72 drives the second ball joint 731 to rotate. At this time, the axial distance between the first ball joint 732 and the second ball joint 731 begins to shorten, and the sliding seat 74 slides along the X-axis. The first ball joint 732 is on the rotating seat 731. 2. The second ball head 731 performs spherical motion on the sliding seat 74. The sliding seat 74 drives the main wind vane 62 to rotate counterclockwise through the main blade connecting rod 61. When the main blade transmission part 10 moves, the secondary blade transmission part 8 also moves accordingly. When the first output gear 7 rotates, the transmission part 81 meshes with the first output gear 7 and the transmission part 81 meshes with the second output gear 82. The second output gear 82 drives the secondary blade group 9 to move along the Z-axis. At this time, the secondary blade group 9 rotates outward to the limit position.

[0044] Preferably, the first output gear 7 rotates clockwise or counterclockwise without affecting the rotation direction of the main blade group 6 and the secondary blade group 9. Since the universal joint 73 is parallel to the X-axis and at its farthest distance in the initial state, rotating counterclockwise or clockwise shortens the distance between the sliding seat 74 and the rotating seat 72, thus not affecting the rotation direction of the main blade group 6. At this time, the lifting plate 84 is at its lowest point, and rotating counterclockwise or clockwise raises the lifting plate 84, thus not affecting the rotation direction of the secondary blade group 9.

[0045] Preferably, the first output gear 7 has teeth 711 formed on it, so that it can mesh with the transmission member 81, thereby driving the secondary blade group 9 to swing once.

[0046] Preferably, the number of teeth 711 of the first output gear 7 is the same as that of the transmission member 81 and the second output gear 82, so that the rotational speeds of the first output gear 7, the transmission member 81 and the second output gear 82 are the same.

[0047] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, as a further explanation of the cooperation between the secondary blade group 9 and the drive module 1 in this embodiment, the secondary blade transmission unit 8 includes a second output gear 82 that is connected to the transmission member 81, a rotating plate 83 that is connected to the second output gear 82, and a lifting plate 84 that cooperates with the rotating plate 83. The secondary blade group 9 is connected to the lifting plate 84. The rotating plate 83 is provided with at least two abutting posts 77. The abutting posts 77 rotate with the rotating plate 83 and apply lifting and lowering forces to the lifting plate 84 in sequence, thereby driving the secondary blade group 9 to swing.

[0048] Specifically, the lifting groove 841 is formed on the lifting plate 84, and the abutting column 77 is formed on the rotating plate 83. The lifting groove 841 includes a lifting section and a lowering section. The lowest point of the lifting plate 84 is formed between the lifting section and the lowering section. The ends of the lifting section and the lowering section form an entrance and exit for the abutting column 77 to enter and exit, and the entrance and exit constitute the highest point of the lifting plate 84.

[0049] In fact, the two ends of the lifting groove 841 are arc-shaped, the middle section is horizontally arranged, the abutting column 77 is at the lowest point of the lifting groove 841, which is actually the midpoint of the lifting section and the lowering section, and the entrance and exit of the lifting groove 841, as well as the lowest point, are located on the trajectory circle of the abutting column 77.

[0050] Further, since the abutting column 77 performs a circular motion, the abutting column 77 has a downward movement tendency in the lowering section, and abuts against the lower groove wall of the lifting groove 841 to lower the lifting plate 84 until the rotating plate 83 rotates to the middle section of the lifting groove 841. At this time, the lifting plate 84 is at the lowest position. With the continuous rotation of the rotating plate 83, the abutting column 77 enters the lifting section. At this time, the abutting column 77 has a tendency to move upward, and abuts against the top of the lifting groove 841 to lift the lifting plate 84, thereby realizing the up-and-down movement of the lifting plate 84.

[0051] Wherein, the rotating radius of the abutting column 77 is R, the lowering distance of the lifting plate 84 is X, the length of the lifting groove 841 is L, and the rotating angle of the secondary blade group 9 is θ. When R becomes larger, X also becomes larger, and θ also becomes larger. R, X, and θ do not change with the change in the number of abutting columns 77. However, if the number of abutting columns 77 increases, R remains unchanged, and L needs to be shortened accordingly. When L becomes shorter, X becomes smaller, and θ also becomes smaller. If the abutting columns 77 are not evenly divided, they cannot uniformly cooperate with the primary blade group 6 during rotation. If the distance between two abutting columns 77 is too close, L needs to be changed accordingly, otherwise it is easy to cause the simultaneous entry of the two abutting columns 77 into the lifting groove 841, and when moving to the middle section of the lifting groove 841, the two abutting columns 77 will perform opposite actions, thereby causing damage to the mechanism.

[0052] The rotating plate 83 is provided with two oppositely arranged abutting columns 77. The abutting column 77 includes a first column body 831 and a second column body 833 arranged oppositely. When the primary blade group 6 rotates one revolution, the first column body 831 and the second column body 833 enter the lifting groove 841 once, respectively, to realize the swing of the primary blade group 6 once and the swing of the secondary blade group 9 twice.

[0053] As Figure 6As shown, the secondary blade assembly 9 further includes a rotating shaft 92 and secondary guide vanes 91 disposed on the rotating shaft 92. The rotating shaft 92 is provided with a transmission gear 85, and the lifting plate 84 has teeth formed on both sides. Since the teeth mesh with the transmission gear 85, when the lifting plate 84 moves up and down, the rotating shaft 92 rotates, thereby causing the secondary guide vanes 91 to swing up and down. When the lifting plate 84 descends, the two secondary guide vanes 91 rotate inward and move closer together. When the lifting plate 84 rises, the two secondary guide vanes 91 rotate outward.

[0054] like Figure 7 As shown, preferably, a plug-in protrusion 821 is provided on the second output gear 82, and a fixing groove 832 for the plug-in protrusion 821 to be inserted is provided on the rotating plate 83, so that the rotating plate 83 rotates with the second output gear 82 and makes assembly more convenient.

[0055] Preferably, the main blade group 6 is rotated to the air outlet end, and the secondary blade group 9 is rotated to the air inlet end. The main blade group 6 rotates to change the air outlet direction, and an air passage is formed between the main blade group 6 and the secondary blade group 9. The secondary blade group 9 rotates to change the size of the air passage. The main blade group 6 controls the air guiding direction, and the secondary blade group 9 controls the air volume. The main blade group 6 and the secondary blade group 9 work together to swing and achieve the air sweeping function.

[0056] Specifically, when the secondary blade group 9 swings outward to both sides and comes into contact with the outer wall of the internal air duct of the housing 5, the air flows between the two secondary blade groups 9, and the air volume is the largest at this time. When the secondary blade group 9 swings inward and comes into contact with the inner wall of the internal air duct of the housing 5, the air flows between the secondary blade group 9 and the outer wall of the internal air duct, and the air is split into two streams and discharged, reducing the air volume.

[0057] Preferably, the main air vane 62 has a turbulence groove 63 formed on it. The turbulence groove 63 can turbulent the airflow, thereby reducing the wind speed and the impact force of the airflow, so as to achieve a windless user experience.

[0058] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
